- 2,6 - naphthalene acid ester glycol in the two-thick ring so that the ratio of PET has a higher strength and modulus, chemical stability and hydrolysis stability, gas barrier, thermal stability, heat Oxygen and ultraviolet stability barrier. The NDA great difficulty in refining, mainly ester exchange.
PEN's excellent performance, so that the application of broad, PEN because of the high modulus and thermal stability, the burning of the water, can be used for high-strength fibers, films can be made for the film or the electronics industry. PEN PET more than temperature, more barriers and a series of recovery, so the container and packaging areas, especially in a better position on the beer packaging. |
